This page contains the source code with binaries, manual, and schematic for the KTM-2 terminal.

NOTE:

The 60 key binary files ARE NOT for a standard KTM-2. These files have been modified for a
60 key verses the
KTM's 54 key keyboard. Procedures on how to use your original ROMS and these files are located
else ware. Files ending with .RAE can be downloaded directly into your SYM using
RAE and the SYM Link program.

I have included some notes and prints showing how and where I added the
extra keys for the larger keyboard that work correctly with the above 60 key
code. Cross-points circled in blue are the added
keys. I also needed to change the existing keys matrix with new ASCII values to
correctly display the new ASCII code. Example would be on the original KTM, a
shift 2 displays an ", whereas on a normal keyboard the shift 2 is an @
character. These are also shown in the schematic, but are not highlighted. Below
is the mapping table showing the binary bites and the corresponding ASCII code
generated for both keyboards.
